We look at the division of 186223 by 57 
The aim is to understand the frequency of 57 in 186223.

Let's proceed to step 1:
57 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 57

On to step 2:
When dividing 18 by 57, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 57

Step 3:
The number 57 fits into 186 3 times, leaving a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 171 from 186 leaves us with 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 57

Let's proceed to step 4:
57 goes into 152 2 times with a remainder of 38.
The next digit of our result is 2. 
Result so far: 32.0
The remainder is 38 after subtracting 114 from 152.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 57

On to step 5:
382 divided by 57 is 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 326.0
If we subtract 342 from 382, we get 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 57

Going ahead to step 6:
When dividing 403 by 57, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 3267.0
Deduct 399 from 403 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
When dividing 40 by 57, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3267.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
400 divided by 57 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 3267.07
Subtract 399 from 400 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
57 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 3267.07
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 57, we get 1 and a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 3267.0701
Subtracting 57 from 100 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 11:
57 goes into 430 7 times with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 3267.07017
Subtracting 399 from 430 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 12:
When dividing 310 by 57, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3267.070175
Deduct 285 from 310 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
The number 57 fits into 250 4 times, leaving a remainder of 22.
The next digit of our result is 4. 
Result so far: 3267.0701754
Subtracting 228 from 250 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
220 divided by 57 is 3 with a remainder of 49.
The next digit of our result is 3. 
Result so far: 3267.07017543
Deduct 171 from 220 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 3267.07017543 with a remainder of 4.9e-08.
